Predicting Dewatering Requirements of an Open Pit within a

A groundwater model, calibrated to this large recharge stress, is more reliable than a model based only on the results of short-term hydrogeological testing. The calibrated model was used to predict passive inflow to the proposed open pit and active dewatering requirements, in order to reduce residual passive inflow to a manageable amount under

Chapter 8 Groundwater Resource Evaluation HWB

The techniques of groundwater resource evaluation require an understanding of the concept of groundwater yield, and, perhaps surprisingly, this turns out to be a difficult and ambiguous term/to address. The concept is certainly pertinent, in that one of the primary objectives of most groundwater resource studies is the determination of the

sustainable yield of groundwater, safe yield, groundwater

Excessive groundwater pumping can lead to groundwater depletion, and this may have serious social and economic consequences. Attempts to limit groundwater pumping have been commonly based on the concept of safe yield, defined as the attainment and maintenance of a long term balance between the annual amount of ground water withdrawn by pumping and the annual amount of recharge.

PROJECT WATER BALANCE MODELLING SUMMARY

the groundwater flow would occur). Such a dynamic results in the groundwater flow being along a very steep gradient that limits the zone of influence of any drawdown created by depressurisation of the potentiometric head of the groundwater at the free surface (i.e. at the quarry face). Hence groundwater inflows will be minimal.
